Medical science has made such tremendous progress that there is hardly a healthy human left. --Aldous Huxley

//edit (Sept 23th 2016): A horrible post of mine. A thread title with a particular statement ("Vaccines stop us from evolving") only to be followed by a post of zero content. Just a reposting of other people's work, none of which provide any conclusive evidence whatsoever for said statement. I should delete this post, but the first two links are actually not half bad, so I'll leave them be and scratch everything else including the thread title.
